WordPress url redirect better approach

. . . . how are you all doing

I have a wordpress blog with 29 posts. The URL structure was

http://www.domain.com/category/cat_name/post_name/

which I have changed to

http://www.domain.com/post_name/

using the permalink settings. I also wanted my older links to work so I did redirects using htaccess

Redirect 301 /categories/cat_name/post_name/ /post_name/

I have checked all links and they are working.

Now what I need to know that is this a good approach or is their a better approach to do it. Doing redirects for 29 links?
